Enermax Pro82+ 625W Power Supply Review

+12V Ripple

The Enermax Pro82+ finishes our tests with flying colors by doing extremely well in the +12V ripple test. With a maximum ripple of 31mV, it stays well within ATX specification while performing on par with two of the more highly-regarded power supplies in this wattage category.

Heat & Acoustical Properties

If we were impressed by the results posted by the Pro82+ in our load tests, we were downright stunned by how quiet it was throughout the testing period. This is actually the first power supply I actually had to check on to make sure the fans was actually spinning. To us, the word “silence” isn’t something to be brought into the open very often since there are hardly and computer components that can truly be called silent. Quiet yes, silent no but damn be if this isn’t the closest thing to silent I have come across with a fan on it. The 120mm fan which Enermax uses here seems to make excellent use of the Air Guard feature we saw earlier in order to produce the quietest power supply we have had the pleasure of reviewing.

Amazingly, the low RPMs the fan is able to operate at does not equate overly high interior temperatures. Even after an hour of the SLI OC test, the Pro82+ 625W didn’t exhibit any overly large increase in temperature.
